These files contain everything on the original disc, including useless padding data used to push the game data to the outer edge of the physical disc for faster reading.
• What is a WBFS file? WBFS stands for Wii Backup File System. It was developed by homebrew coders to store Wii games on a USB hard drive without wasting space. Unlike an ISO, a WBFS file removes the padding data and can compress the game.
